What is the maximum weight allowed for lithium metal batteries on SkyWest aircraft?

The maximum weight allowed for lithium metal batteries on SkyWest aircraft is under 2 grams. This limitation is rooted in safety protocols established for the transport of lithium batteries, which can pose fire risks if they are damaged or short-circuited. By restricting the weight of lithium metal batteries to under 2 grams, airlines like SkyWest minimize the potential dangers associated with carrying these batteries in the cabin or cargo areas. This regulation aligns with general aviation safety practices, where lighter batteries carry a lower risk profile.

Larger weights, such as those exceeding 2 grams, typically necessitate stricter packing and labeling requirements, or may even be prohibited from transport by certain airlines. Hence, the correct answer reflects the precautionary measures taken to ensure the safety of passengers and crew aboard SkyWest flights.
